A cybernetic model to predict the low-growth-rate behavior of bacteria in mixed-substrate environment is presented. Using only growth and maintenance parameters from single-substrate experiments, the model accurately predicts the simultaneous substrate utilization and maintenance energy effects in constant fed-batch cultures of Klebsiella oxytoca. The robustness of the model was examined more r...

Hypervirulent variants of Klebsiella pneumoniae have been primarily reported in the Asian Pacific Rim, but they are spreading across the globe. We report the sequence of K. pneumoniae strain hvKP1, which caused liver-splenic abscesses in an otherwise healthy 24-year-old from Buffalo, NY, which will assist in determining why these variants are more pathogenic than "classic" K. pneumoniae strains.

We present the draft genome sequence of a Klebsiella pneumoniae carbapenemase (KPC)-producing sequence type 258 (ST258) K. pneumoniae strain, ST258_FL. Uniquely, strain ST258_FL harbors two copies of the blaKPC gene on the chromosome, one of which is integrated into a prophage.

We report here the complete genome sequence of Klebsiella pneumoniae strain HKUOPLC, isolated from a giant panda fecal sample collected from Ocean Park, Hong Kong. The complete genome of this bacterium may contribute to the discovery of efficient cellulose-degrading pathways.

We report here the draft genome sequence of Acinetobacter baumannii strain M3AC14-8, sequence type 2 (ST2), carrying a chromosomally carried blaKPC-2 gene. The draft genome consists of a total length of 4.11 Mbp and a G+C content of 39.25%.

We sequenced the first blaVIM-1-positive Klebsiella pneumoniae strain isolated in Singapore. The isolate belongs to multilocus sequence type 2542 (ST2542), and blaVIM-1 was the first gene in an integron that also contained aacA4, aphA15, aadA1, catB2, qacEdelta1, and sul1.

Plasmid pKP12226 was extracted and analyzed from a CTX-M-15-producing Klebsiella pneumoniae sequence type 11 (ST11) isolate collected in South Korea. The plasmid represents chimeric characteristics consisting of a pIP1206-like backbone and lysogenized phage P1-like sequences. It bears a resistance region that includes resistance genes to several antibiotics and is different from previously char...

INTRODUCTION Frequency of extended-spectrum beta-lactamases (ESBLs) and its variants may vary in different geographical areas, as reports indicate their spread in some certain communities. The aim of this study was to determine the frequency of ESBLs in strains of Klebsiella and E. coli, isolated from patients hospitalized in teaching hospitals of Yazd. METHODS This cross-sectional study was ...

Klebsiella pneumoniae is a major threat to public health, causing significant morbidity and mortality worldwide. The emergence of highly drug-resistant strains is particularly concerning. There has been a recognition and division of Klebsiella pneumoniae into three distinct phylogenetic groups: Klebsiella pneumoniae, Klebsiella variicola, and Klebsiella quasipneumoniae. K. variicola and K. quas...

Klebsiella species is the second most commonly isolated gram-negative organism in sepsis and a frequent causative pathogen in pneumonia. The receptor for advanced glycation end products (RAGE) is expressed on different cell types and plays a key role in diverse inflammatory responses. We here aimed to investigate the role of RAGE in the host response to Klebsiella (K.) pneumoniae pneumonia and ...
